  • Patent number: 4396146
    Abstract: A container made from an integral blank in which a solid bottom wall is provided with hingedly connected side walls and ends walls which may be folded normal thereto. The end walls are provided with additional panels which may be placed in surface-to-surface relation with the interior of the side walls and secured thereto in any suitable manner as by any automatic machinery such as a "tray former". A pair of the securement panels from opposite end walls and opposite corners of the box have extensions which may be folded inwardly toward the opposite side wall panel to form a central partition. These extensions are longer than half the transverse distance between the opposite side walls so that portions of the extensions may meet in surface-to-surface relation to form a partition.
